Aluminium Ageing Oven

Sistem Teknik designs and produces aluminium aging ovens (AAOs) for the artificial aging of profiles after the extrusion process. 

Our company offers double-length (up to 16 metres) aging ovens up to 24 baskets as well as single-length (up to 8 metres) aging ovens up to 12 baskets with automatic unmanned operation by special loading/unloading cars.

AAOs can be heated through indirect gas or electricity. The oven is heated up to 185 °C in less than 1 hour while the entire heat treatment process lasts for 6 hours, allowing the application to take place 4 times a day.

By means of a recirculation fan, the hot air generated in the thermoblock(s) is directed into the oven at a useful volume. Depending on the desired time intervals during heating up, the fan discharge directions are rotated in the forward and backward directions to achieve temperature homogeneity at material temperatures in the range of ± 3 ° C (the reversible end flow system).

By means of the reversible end flow system (changeable air flow direction); perfect temperature distribution is achieved in order to ensure excellent hardness results in the charged materials over the whole length of the profiles. 

While 2 transfer cars located at the entrance and exit zones carry out the loading and unloading procedures, chain or roller conveyor systems can also be used.
